VALVE.

Application filed July 19, 1923. Serial N0. 652,476.

To all fwlwmt may concern: v Y v Be it known that I, Gnovnn S. EBLn a citizen of the United States, andresident of the borough of Manhattan, city, county, andy State of New York, have invented certain new and useful Improvements in Valves, of which the followingis a specification.

My invention relates to valves controlling` the passage of uids, and particularly to mixing valves of the type allowing one or the other of two fluids (for instance hot and cold water) to be discharged, or a mixture of both in varying proportions. .The object of my invention isto provide a simple construction of this character which will be readily assembled and taken apart, in which the joints will remain tight, andfin which the moving valve members will be held securely in their proper positions.

A typical example of a structure embodying mypresent invention is illustrated by the accompanying drawings, in which Fig. 1 is a central'vertcaly section on line 1-1 of Fig. 2, the latter being a plan View, with parts in section; Fig. 3 is a partial vertical sectionon line 3-3 of Fig. 2; Figs. 4 and 5 are vertical sections on lines 4 4 and 5-5 respectively of Fig. 1; Figs. 1 to 5 show the closed or shut position of the valve; Fig. 6 is a diagrammatic sectional plan illustrating the position of the valves proper and of the cam controlling them, at a time when only' one of them (the cold water valve) is open; Fig. 7 is a similarl diagram showing the parts inthe mixing position `(both valves open) g" and Fig. 8 is a like diagram illustrating said parts in the position with only the other valve (the hot water valve)` open.

The valve casing comprises a lower member and an upper member (the terms upper and lower being used for the sake of convenience, and not as implying tha-tthe` parts are operative only inv this position). The lower member, 15, has three connections f or bosses, preferably screw threaded to receive the usual pipin (not shown), two of these bosses, 16 and 1 which'are represented as diametrically opposite, serving asinlets for the fluid (cold and hot water respectively) to a central chamberx18, while the third, 19, serves as an outlet for the iiuid from said chamber. in permanent communication with the chamber' 18, but the 'connection of the' inlets 16 and 17 lwithsaid chamber Tis controlled by This outlet is shownl asV valves constructed as follows, inthe specific example illustrated: Each of these valves comprises a guide member or stemf 20 of substantially square or other suitable cross section (see especially Fig. 4) fitted to slide radially in the casing member 15, in a cylindrical guideway 15. Passages 21 are thus provided through which the water may iiow along the stem 2O when the` valve is open. At one end, the stem has ascrew threaded recess to receive a threaded shank or pin 22 projecting from an inner member 23, located in the chamber 18 and having a recess in which is seated the `washer 24,of rubber or.

23 on the member 23,and a slot 20 (for the insertion of a screw-driver) on the stem 20.

The washer 24 forms the sealing member orv valve proper, adapted to become seated outwardly on the member 15 at the inner end of the guideway 15, a finished surface 15 being preferably provided to properly seat the washer. i

It will be notedthat the pressure of the water entering then-bosses 16, A17 and the channels or passages 21 tends toopen the two inlet valves To close these valves, and to control their opening movement, I have provided a cam 25, secured to a spindle 26 rotatable about the axis of the casing member 15. The configuration oroutline of this cam is such as to secure the operation set forth hereinafter. The cam is in engagement with balls 27'projecting inwardly fro-m longitudinal recesses provided in the mem`- bers 23, said recesses also containing springs 28 tending to project said balls, these springs Vcompensate for` any inaccuracies in the construction or machining of the valves and the parts cooperatingtherewith; with the use of these springs, .the dimensions ofthe parts may vary within a relatively wide tolerance range, and yet thevalves will seat and operate properly. y, Y

The mere loosening of the nut 39 will not enableeanperson to remove the handle 40' or the spindle 26, or in fact anything but the packing 37, which is of little value.

The position of the handle 40 and of the dial on which it indicates, will not be disturbed, and the manner of operating the device will be exactly the same as before. This is of especial advantage as it enables one to supply hot water either from the left or the right, thus simplifying the piping and in certain relations, avoiding the crossing of the cold-water pipes with the hot-water pipes, for instance, when such pipes are connected with two or more devices.

Various modifications may be made without departing Jfrom the nature of my invention as set forth in the appended claims.

I claim:

l. A device of the class described, com` prising a casing composed of two members one ot' which is Jformed with a chamber having two inlets and an outlet, a cam mounted to turn in said chamber, valves controlling said inlets and movable radially with respect to the cam axis, and governed by said cam, a handle, journaled in the other casing member, for actuating said cam, and a washer compressed between the two casing members to form a tight joint between them, said washer and said valves being provided with cooperating stop elements to prevent separation of the valves 'from the casing member having the inlets, when the valve-controlling cam is withdrawn.

2. A device of the class described, comprising a casing formed with a chamber having two inlets and an outlet, said casing being composed of two members, a cam mounted to turn in said chamber, valves controlling said inlets and movable toward and from the axis of the cam, and governed by said cam, a handle, journaled in one ot casing members, for actuating said cam, and a washer compressed between said casing members to form a tight joint, between them, said washer and said valves being provided with cooperating stop elements to prevent separation of the valves when the ,valve controlling cam is withdrawn.
